It also includes overall homicide rates for 29 and 21 (for which detailed data are not yet available). Data in this report are from the FBI s Supplementary Homicide Reports (SHR), unless otherwise noted. The SHR Program of the FBI collects yearly supplementary homicide data regarding homicides committed in the United States. Statistics in this report detail homicide trends by age, sex, and race, including homicides of children under age 5 and of persons age 65 or older. It examines the relationship between the victim and the offender, particularly in cases of intimate and family homicide. The report also examines multiple victim and offender homicides, circumstances surrounding the death, justifiable homicides, law enforcement officers killed, homicides cleared, and homicide trends by city size and weapon use. These data may differ slightly from previously published versions because of updates to the data file, changes to the imputation methods used, and refinements in the analyses. (See Methodology for more information on the imputation methods used in this report.) In addition, analyses presented here include data from 198 through 28 only. This modification was made, in part, to reflect revisions in the SHR in 198. The SHR are available at the National Archive of Criminal Justice Data. Spreadsheets used to generate the figures in this report are available on the BJS website. BJS

(See Methodology for information on rate calculations.) In 198 the rate peaked at 1.2 per 1, and subsequently fell to 7.9 per 1, in The rate rose again in the late 198s and early 199s to another peak in 1991 of 9.8 per 1,. The homicide rate declined sharply from 9.3 homicides per 1, in 1992 to 4.8 homicides per 1, in 21. The number of homicides reached an all-time high of 24,73 homicides in 1991 then fell rapidly to 15,522 homicides by 1999 The number of homicides increased steadily from the early 195s until the mid-197s (figure 2). Between 1999 and 28, the number of homicides remained relatively constant, ranging from a low of 15,552 homicides in 1999 to a high of 17,3 homicides in 26. These homicide numbers were still below those reported in the 197s, when the number of reported homicides first rose above 2, (reaching 2,71 in 1974). 5, Note: Data are based on annual estimates of homicide from previously published versions of Crime in the United States.

3 The demographic characteristics of homicide victims and offenders were different from the characteristics of the general population Based on available data from 198 to 28 Blacks were disproportionately represented as both homicide victims and offenders. The victimization rate for blacks (27.8 per 1,) was 6 times higher than the rate for whites (4.5 per 1,). The offending rate for blacks (34.4 per 1,) was almost 8 times higher than the rate for whites (4.5 per 1,) (table 1). Males represented 77% of homicide victims and nearly 9% of offenders. The victimization rate for males (11.6 per 1,) was 3 times higher than the rate for females (3.4 per 1,). The offending rate for males (15.1 per 1,) was almost 9 times higher than the rate for females (1.7 per 1,). Approximately a third (34%) of murder victims and almost half (49%) of the offenders were under age 25. For both victims and offenders, the rate per 1, peaked in the 18 to 24 year-old age group at 17.1 victims per 1, and 29.3 offenders per 1,.

The homicide victimization rate for children under age 14 was the lowest of all age groups, peaking in 1993 at a high of 2.2 homicides per 1,. By 24, this rate had declined to the lowest level recorded 1.4 homicides per 1, and remained stable through 28 at 1.5 homicides per 1, (figure 3). The homicide victimization rate for teens (14 to 17 years old) increased almost 15% from 4.9 homicides per 1, in to 12. homicides per 1, in Since 1993, the victimization rate for teens has declined to 5.1 homicides per 1,. In 28, young adults (18 to 24 years old) experienced the highest homicide victimization rate (13.4 homicides per 1,). In the early 198s, 25 to 34 year-olds had the highest homicide victimization rate 18.6 homicides per 1,. By 28, this rate had fallen to 1.7 homicides per 1,, a 42% reduction. Homicide victimization rates for adults ages 35 to 49 and 5 or older have remained stable since 1999 at between 5.7 and 5.9 homicides per 1, for adults ages 35 to 49 and between 2.5 and 2.7 homicides per 1, for adults ages 5 or older. Homicide offending rates followed a pattern similar to victimization rates The offending rates for teens (14 to 17 years old) and young adults (18 to 24 years old) increased dramatically in the late 198s while the rates for older age groups declined (figure 4). From 198 to 28, young adults (18 to 24 years old) have consistently had the highest offending rate. This rate nearly doubled from to 1993, going from 22.1 offenders per 1, young adults to 43.1 offenders per 1,. Since 1993, the offending rate for 18 to 24 year-olds has declined to 24.6 offenders per 1, in 28. The offending rate for teens (14 to 17 years old) increased substantially from 1.4 offenders per 1, in to 3.7 offenders per 1, by After 1993, the rate fell so much that by 2, the offending rate for teens was near its level, at 9.5 offenders per 1,. The offending rates for adults ages 35 to 49 and 5 or older have remained relatively stable since 2, at between 4.8 and 5.1 offenders per 1, for adults age 35 to 49 and between 1.3 and 1.5 offenders per 1, for adults age 5 or older. 4 Homicide Trends in the United States,

5 After many years of decline, the average age of both victims and offenders has leveled off The average age of victims fell from 34.1 years in 198 to 31.3 years in 1994, then increased to 32.7 years by 28 (figure 5) offenders fell from 29.6 years in 198 to 26.4 years in 1994, then increased to 28.8 years in 28 both offenders and victims increased slightly in recent years, yet remained lower than they were prior to the late 198s. The age distribution of homicide victims and offenders differed by type of homicide From 198 to 28 A quarter of the victims (24%) of gang-related homicides were under age 18. Juveniles were also a fifth (19%) of persons killed by family members, and they represented more than a quarter (28%) of persons killed by arson or by poison (table 2). Victims age 5 or older were 39% of workplace homicide victims and 34% of victims of homicide by poison. Younger victims were more likely than older victims to know the offender (figure 6) FIGURE 5 Average age of homicide victims and offenders, Mean age 4 Victims 3 Offenders FIGURE 6 of homicides in which offender was known to victim, by age of victim, Age of victim TABLE 2 Homicide type, by age, Victims Offenders Total Under or older Total Under or older All homicides 1% 1.% 53.2% 22.8% 14.% 1% 11.% 65.5% 17.1% 6.5% Victim/offender relationship Intimate 1% 1.3% 48.5% 33.6% 16.6% 1% 1.% 47.% 34.7% 17.2% Family 1% % Infants 1% 1 1% Elders 1% 1 1% Circumstances Felony murder 1% 7.5% 48.2% 22.2% 22.1% 1% 14.6% 72.7% 1.7% 2.% Sex related 1% % Drug related 1% % Gang related 1% % Argument 1% % Workplace 1% % Weapon Gun homicide 1% 8.1% 59.7% 22.% 1.3% 1% 12.2% 65.9% 15.1% 6.9% Arson 1% % Poison 1% % Multiple victims or offenders Multiple victims 1% 17.9% 47.% 19.3% 15.8% 1% 9.5% 66.3% 18.3% 5.9% Multiple offenders 1% % Note: Detail may not sum to total due to rounding. The percentages of victim/offender relationships are based on the 63.1% of homicides from 198 through 28 for which the victim/offender relationships were known. The percentages of homicides involving multiple victims or offenders were known for 69.1% of incidents. NOVEMBER 211 5

FIGURE 8 Homicide victimization rates for children under age 5, by race of victim, Rate per 1, White Black Other* CHILDREN UNDER AGE 5 The homicide rate for children under age 5 has remained stable or declined for all racial groups The number of homicides of children under age 5 declined between 1993 and 26, but increased in 27 and 28 (figure 7). Homicide rates for black children under age 5 declined 36% between 1993 and 28, dropping from 11.3 homicides per 1, in 1993 to 7.2 homicides per 1, in 28 (figure 8). black children under age 5 have remained substantially higher than rates for white children or children of other races. white children under age 5 remained relatively stable between 198 and 199, with an average rate of 2.4 homicides per 1,. The rate rose to 2.8 homicides per 1, by 1996, then dropped down to 2.1 homicides per 1, in 26. Since 26 the rate has risen slightly to 2.3 homicides per 1, in 28. In general, the younger the child, the greater the risk for being the victim of a homicide (figure 9) Throughout the 28-year period from 198 to 28, infants under 1 year of age had the highest homicide victimization rate of all children under age *Other race includes American Indians, Alaska Natives, Asians, Hawaiians, and other Pacific Islanders.

7 A parent was the perpetrator in the majority of homicides of children under age 5 (figure 1) Of all children under age 5 murdered from 198 through 28 63% were killed by a parent 33% were killed by their fathers and 3% were killed by their mothers (table 3) 23% were killed by male acquaintances 5% were killed by female acquaintances 7% were killed by other relatives 3% were killed by strangers. Of children under age 5 killed by someone other than their parent, 8% were killed by males (not shown).

FIGURE 11 of homicides of children under age 5, by sex of victim and offender, Most of the victims and offenders of homicides involving children under age 5 were male Since 198, the number of homicides involving male children under age 5 killed by male offenders increased dramatically in the early 199s before dropping in 1997 (figure 11) followed a similar pattern for female victims killed by male offenders, although the changes were less pronounced.

Between 198 and 28, males accounted for nearly 6 out of 1 homicide victims age 65 or older. Since 2 the number of homicides involving elderly males (age 65 or older) has increased slightly, while the number involving elderly females has decreased (figure 12). The homicide victimization and offending rates for persons age 65 or older have been relatively stable since 21, ranging from a high of 2.1 victims and.8 offenders per 1, in 23 to a low of 1.7 victims and.6 offenders in 27. In 28, both victimization and offending rates for persons age 65 or older remained low at 1.9 victims and.7 offenders per 1, (figure 13). Older homicide victims were more likely to have been killed during a felony than younger victims (figure 14) Homicides committed during a felony were those that occurred in conjunction with a serious crime, usually punishable by at least one year in prison, such as rape, robbery, burglary, or arson. Between 198 and 28, the percentage of homicides that occurred during a felony was higher for elderly homicide victims age 65 or older than for homicide victims of other ages. Among murder victims ages 2 to 4, the percentage of homicides committed during a felony was relatively stable, ranging from 17.7% to 19.3% of all homicide victims in this age group. Among murder victims age 4 or older, the proportion of homicides committed during a felony began increasing, accounting for 32.8% of homicides of 64-year-old victims and 4.3% of homicides of 76-year-old victims. 8 Homicide Trends in the United States,

Victimization rates for both males and females have been relatively stable since 2 Males were nearly 4 times more likely than females to be murdered in 28 (figure 15). The homicide victimization rate for both males and females was at its highest in homicides per 1, for males and 4.5 homicides per 1, for females. By 28, the rates for both groups had fallen, reaching 8.5 homicides per 1, for males and 2.3 homicides per 1, for females. Homicide offending rates for both males and females followed the same general pattern as homicide victimization rates Males were 7 times more likely than females to commit murder in 28 (figure 16). The offending rate for females has declined from 3.1 offenders per 1, in 198 to 1.6 offenders per 1, in 28. The offending rate for males peaked in 1991 at 2.8 per 1,, then fell to a low of 11.3 per 1, in 28.

10 The sex distribution of homicide victims and offenders differed by type of homicide From 198 to 28, among all homicide victims Females were more likely than males to be the victim of intimate killings (63.7%) and sex-related homicides (81.7%) (table 5). Males were more likely to be involved in drug- (9.5%) and gang-related homicides (94.6%). The relationship between the victim and the offender differed for female and male victims Female murder victims (41.5%) were almost 6 times more likely than male murder victims (7.1%) to have been killed by an intimate (table 6). More than half (56.4%) of male murder victims were killed by an acquaintance; another quarter (25.5%) were murdered by a stranger.

11 Trends by race Blacks were disproportionately represented among homicide victims and offenders In 28, the homicide victimization rate for blacks (19.6 homicides per 1,) was 6 times higher than the rate for whites (3.3 homicides per 1,). The victimization rate for blacks peaked in the early 199s, reaching a high of 39.4 homicides per 1, in 1991 (figure 17). After 1991, the victimization rate for blacks fell until 1999, when it stabilized near 2 homicides per 1,. In 28, the offending rate for blacks (24.7 offenders per 1,) was 7 times higher than the rate for whites (3.4 offenders per 1,) (figure 18). The offending rate for blacks showed a similar pattern to the victimization rate, peaking in the early 199s at a high of 51.1 offenders per 1, in After 1991, the offending rate for blacks declined until it reached 24 per 1, in 24. The rate has since fluctuated, increasing to 28.4 offenders per 1, in 26 before falling again to 24.7 offenders per 1, in 28.

13 Most murders were intraracial From 198 through 28 84% of white victims were killed by whites (figure 19). 93% of black victims were killed by blacks. FIGURE 2a Stranger homicides, by race of offender and victim, Stranger homicides were more likely to cross racial lines than homicides involving friends or acquaintances 4 White on white For homicides committed by a stranger to the victim, 26.7% were interracial (figure 2a) a friend or acquaintance of the victim, 9.7% were interracial (figure 2b).

In recent years, rates for most groups have stabilized. In 28, young adults (18 to 24 years old) had the highest victimization rate in each racial and sex group. After increases in the early 199s, the victimization rates for both white and black male teens (14 to 17 years old) peaked in 1993 at 9.4 homicides per 1, for whites and 79 homicides per 1, for blacks (figures 21a and 21b). Since 1993, the victimization rates for both white and black male teens (14 to 17 years old) have declined. By 28, the rates for both groups were similar to the rates in the mid-198s, at 4.5 homicides per 1, for whites and 31.4 homicides per 1, for blacks. In 28, black males age 18 to 24 years-old had the highest homicide victimization rate (91.1 homicides per 1,). That rate was more than double the rate for black males age 25 or older (38.4 homicides per 1,) and almost triple the rate for black males age 14 to 17 (31.4 homicides per 1,). Among black males age 18 to 24, the homicide victimization rate was much lower in 28 (91.1 homicides per 1,) than in the late 198s and early 199s, when it reached a high of homicides per 1, in For white females of all ages, homicide victimization rates have declined. Among white women age 18 to 24, the rate declined from 5.5 homicides per 1, in 198 to 2.6 per 1, in 28 (figure 21c). Since 1993, the victimization rate for black females has declined across all age groups. Girls age 14 to 17 experienced the largest victimization rate decline, dropping from 13.1 homicides per 1, in 1993 to 4.6 per 1, in 28 (figure 21d). FIGURE 21d Black female homicide victimization rates, by age, Rate per 1, or older Homicide Trends in the United States,

15 Homicide offending patterns were generally similar to victimization patterns Young adults (18 to 24 years old) had the highest offending rate in each racial and sex category. The offending rate for white male young adults (18 to 24 years old) was 2.4 offenders per 1, in 27 and 28, which was an all-time low (figure 22a). Between 198 and 28, young adult black males had the highest homicide offending rate compared to offenders in other racial and sex categories. The offending rate for black male teens peaked in 1993 at offenders per 1, before declining. In recent years, the black male teen offending rate has increased from 54.3 offenders per 1, in 22 to 64.8 offenders per 1, in 28. The offending rate for black male young adults increased from 25.2 offenders per 1, in 198 to a high of 365. offenders per 1, in 1993 dropped by more than half from 1993 to 28, when it reached an all-time low of offenders per 1, remained more than double the rate of black male teens (64.8 offenders per 1,) and 4 times the rate of black males age 25 or older (37.8 offenders per 1,) (figure 22b). Homicide offending rates among females show White females of all ages had the lowest offending rates of any racial or age groups (figure 22c). The offending rates for black females of all ages has declined since the early 199s. Black female teens experienced the largest decline in offending, dropping from 11 offenders per 1, in 1992 to 3 offenders per 1, in 28 (figure 22d).

Friend/acquaintance includes neighbors, employees, employers, and other known persons. These data are grouped from the original categories. For detailed categories, see appendix table 24a and appendix table 24b for weighted and unweighted data. Young males (14 to 24 years-old), particularly young black males, were disproportionately involved in homicide compared to their proportion of the population Since 2, young white males have accounted for about 6% of the population and about 1% of homicide victims. Their proportion of offenders has declined slightly from 18% in 2 to 16% by 28 (figure 23a). While young black males have accounted for about 1% of the population from 198 to 28, they have made up an increasing proportion of homicide victims, going from 9% of all homicide victims in 198 to 18% in After 1994, their proportion of homicide victims has remained relatively stable at about 16%. The percentage of young black male homicide offenders also increased rapidly from the mid-198s to the early 199s, going from 17% in to 35% by 1993 before declining. By 28, young black males made up about a quarter of all homicide offenders (27%) (figure 23b). Victim/offender relationship Most homicides with known victim/offender relationships involved people who knew each other Since the early 199s, homicides for which the victim/offender relationships were unknown constituted the largest category of homicides (figure 24). The proportion of homicides in which the victim/offender relationships were unknown increased from 36% of all homicides in 198 to 44% in 28. Among homicides for which the victim/offender relationships were known, 22% of victims were killed by strangers More than half (56%) of victims were acquaintances of the assailant (table 8).

17 Homicides by a friend/acquaintance or a stranger were more likely to involve a gun than those committed by an intimate or family member (figures 25a, 25b, 25c, and 25d) Across the 28-year period, the percentage of homicides committed by intimate partners that involved a gun declined from 69% of all intimate homicides in 198 to 51% in 28, a 26% decline. Compared to homicides committed by intimates, friends/ acquaintances, or strangers, homicides committed by a nonintimate family member were more likely to involve weapons other than guns (such as knives, blunt objects, or personal weapons). Among homicides for which the victim/offender relationships were unknown, the percentage of homicides involving a gun increased 33%, from 59% in 198 to 78% in 28 (figure 25e).

The percentage of males killed by an intimate fell from 1.4% in 198 to 4.9% in 28, a 53% drop. For females, the percentage killed by an intimate increased 5% across the same period (figure 26). The percentage of females killed by an intimate declined from 43% in 198 to 38% in. After, that percentage gradually increased, reaching 45% in 28.

The proportion of black males killed by an intimate has declined Among homicides with known victim/offender relationships The percentage of black male murder victims killed by an intimate declined steadily from 13% in 198 to a low of 5% in 28 (figure 27). The percentages of white males and black males killed by an intimate have been relatively similar since 22, at about 5% for both groups. Intimate homicides of white women fluctuated slightly between 198 and 28, averaging 44% of all white female homicides across that period.

The proportion of intimate homicides by a spouse has decreased since 198, while the proportion committed by a boyfriend or girlfriend has increased (figure 28) In 198, the majority (69.1%) of all intimate homicides were committed by a spouse while a quarter of intimate homicides were committed by a boyfriend or girlfriend (26.8%). After 198, the proportion of intimate homicides involving a spouse began decreasing while those involving a boyfriend or girlfriend began increasing. By 28, the proportion of intimate homicides committed by a spouse (46.7%) was nearly equal to the proportion committed by a boyfriend or girlfriend (48.6%). The proportion of male and female intimate homicide victims killed with guns has decreased (figures 29a and 29b) In 198, the majority (68.9%) of male intimate homicide victims were killed with guns and a third (3.5%) were killed with other weapons (knives, blunt objects, or personal weapons). After 198, the proportion of male intimate homicide victims killed with guns gradually declined while the proportion killed with other weapons increased. Since 2, guns have been less prevalent than other weapons in intimate homicides against male victims. By 28, a higher proportion of male intimate homicide victims were killed with weapons other than guns (54.6%) than with guns (41.9%).

20 Female intimate homicide victims showed a similar pattern. In 198, two-thirds were killed by guns (69.5%) and less than a third were killed with other weapons (28.9%). After 198, the proportion of female intimate homicide victims killed by guns decreased while the proportion killed by other weapons increased, although guns were still the most prevalent weapon used by intimate offenders against female victims. In 28, 53% of all female intimate homicide victims were killed with guns while 41% were killed with other weapons. Guns were the most frequently used type of weapon in intimate homicides, but weapon type varied by relationship From 198 through 28 Overall, over two-thirds of victims murdered by a spouse or ex-spouse were killed by guns (table 11). Boyfriends were more likely to be killed by knives than any other group of intimates. Girlfriends were more likely to be killed by force than any other group of intimates.
